Hi, yeah the Built-in Parallax is the Layer property that you can change in the editor from 0-100 to get the feeling of 3d space.
But what I want for my game is
1. I want to stop the parallax effect in my game at some point,
which is it can not be done with the built-in one
2. the variety of screen size might mess up my parallax design,
I want it to stay the at where I design it to be.
